Advanced design security and cost issues: tackling the root causes: ① little cavity, please consult Xiaojing Li 18,620,325,252 (18,620,325,252, also the phone) and by decompression mouth solve the traditional curtain wall troubled by the negative pressure. ② overall curtain wall zoned whole zero, the overall security of the curtain wall into the security issues of the plate. ③ solve the root causes of the problems of safety and cost. Long-term decorative function: better than non-fluorocarbon surface maintenance-free self-cleaning function. Building facades overall energy-saving system is maintenance-free self-cleaning function better than aluminum, aluminum plate facing layer can choose fluorocarbon optional polyurethane \ acrylic paint, while the the building facades overall energy saving board tetrafluoroethylene fluorocarbon the paints and coatings, as we all know, fluorocarbon coated surface energy is very low, minimal coefficient of friction, dust adhesion is extremely difficult, even if the attachment, it is only at the grassroots level surface without the formation of a chemical or physical binding, easy to clean, has recognized the self-cleaning function.
